Filter by:Hypothesis Response guided therapy improves significantly the overall SVR in Hispanics compared to historical control. There is no difference in SVR between patients with an undetectable HCV RNA at week 8 and week 28 who received a 4 week lead-in of PR plus 24 weeks of PR+BOC based treatment and patients with detectable HCV RNA at week 8 and undetectable HCV RNA at week 24 who received a lead-in of PR plus 32 weeks PR+BOC followed by based therapy and 12 weeks of PR.
This study will assess the safety and efficacy of alisporivir plus pegylated interferon alfa2a and Ribavirin as well as boceprevir plus pegylated interferon alfa2a and Ribavirin in African American chronic hepatitis C genotype 1 patients that have never received treatment for their hepatitis C.
Background: - Standard treatment for the hepatitis C virus (HCV) is a combination of the drugs peg-IFN and ribavirin. However, this treatment is not very effective in people with a serious type of HCV (HCV genotype 1) and also in people who have human immunodeficiency virus (HIV) coinfection. Researchers want to add a new drug, boceprevir to see if it can improve treatment results in people with both HCV genotype 1 and HIV. Boceprevir used in combination with peg-IFN and ribavirin has been recently approved for the treatment of people with HCV genotype 1 infection only, and is currently being studied in those with HIV and HCV. Objectives: - To test boceprevir, peg-IFN, and ribavirin as a treatment for HCV genotype 1 in people with HCV monoinfection compared to those with both HIV and HCV infections. Eligibility: - Individuals at least 18 years of age who have HCV genotype 1 infection, and have not received interferon treatment for HCV - Half of the study participants will also have HIV infection. Design: - Participants will be screened with a medical history and physical exam. They will also have blood and urine tests. - Participants will also have heart and liver function tests, and answer questions about mood and depression. - Those in the study will receive ribavirin tablets to take twice a day, and peg-IFN to inject under the skin weekly. - Two weeks after starting treatment, participants will have blood tests to study the treatment. - Four weeks after starting treatment, participants will start taking boceprevir three times a day. - Participants will have regular study visits with blood samples and other tests. The length of therapy will depend on the level of virus detected in the blood at several clinic visits. Those who do not respond well to the medicines at 12 weeks will stop treatment. The full length of treatment is 48 weeks.
This study will evaluate the safety, tolerability, and antiviral activity of grazoprevir (MK-5172) when administered concomitantly with peg-interferon alfa-2b (Peg-IFN) and ribavirin (RBV) to treatment-naïve participants with chronic genotype 2 (GT2) or genotype 3 (GT3) hepatitis C virus (HCV) infections.
This is a study to determine the pharmacokinetics (PK) and weight-based dose of boceprevir following single oral dose administration in Chronic Hepatitis C Virus (HCV) pediatric participants.
The purpose of this study is to determine in genotype 1 Hepatitis C Virus (HCV)-infected participants, the safety, tolerability, pharmacokinetics (how the drug is absorbed in the body, how it is distributed within the body and removed from the body over time) and antiviral activity of repeated doses of TMC649128 given as monotherapy and given in combination with pegylated interferon + ribavirin. We assess the pharmacokinetic/pharmacodynamic (how the study medication affects the body) (PK/PD) relationship for antiviral activity, active metabolite and safety of TMC649128 and its metabolites. We determine the short term safety and tolerability of the co-administration of TMC649128 and pegylated interferon + ribavirin during multiple dosing for 14 days in treatment-naive genotype 1 HCV-infected participants. We explore the effect of pegylated interferon + ribavirin on the pharmacokinetics of TMC649128 during the multiple dosing for 14 days in treatment-naive genotype 1 HCV-infected participants. We also assess in a preliminary way the short term antiviral effect of the combination of TMC649128 with pegylated interferon + ribavirin during a 14-day dosing period in treatment-naive genotype 1 HCV-infected participants.
This is a proof of concept study, designed to look at the safety and antiviral activity of LCQ908 in hepatitis C infected patients.
The investigators evaluated the safety and efficacy of a short lead-in course (8 weeks) of entecavir followed by combination of entecavir plus peginterferon alfa-2a for 40 weeks.
This study will examine whether 12 month treatment with entecavir(Baraclude®) has an effect on changes of liver stiffness measurement (LSM) and of hyaluronan measurement in patients with chronic hepatitis B infection.
This is a non-interventional study designed to evaluate the efficacy and safety of combination study drugs in the treatment of participants diagnosed with Chronic Hepatitis C (CHC). CHC participants with confirmed positive hepatitis-C virus (HCV) RNA in plasma, and who have not been previously treated with the Pegylated interferon (PegIntron) Pen, were enrolled into study.
